Key Questions Answered

• •Strategic Diplomacy: Anthemius renewed peace treaties with Sassanid Persia immediately upon taking power, preventing two-front warfare and keeping lucrative Asian trade routes open while focusing military resources on northern Hun threats along the Danube frontier.
• •Political Transition Management: Seven-year-old Emperor Theodosius II's succession in 408 CE proceeded smoothly because Anthemius provided continuity of leadership and policy, demonstrating how competent regents enable stable transfers of power during vulnerable child-emperor periods.
• •Catastrophic Policy Failure: Olympius ordered genocide of Gothic families in Italian cities in 408 CE, immediately driving 12,000 trained Gothic warriors from Roman service to Alaric's army and transforming him from marginalized figure to major military threat overnight.
